I checked the above post, but there has been no answer for over 2 months.
I just discovered this browser today. I guess it was installed when I upgraded to 14.04 a few weeks ago.
Here are the photos of what I get when I run it.
Full screen with no menu (its small but mouse is in top left corner)
(I have dual monitors, the blue border on the right is the next monitor. I reduced the size not to consume excess bandwidth on viewers.)
I would like to either repair or remove it. I have searched for install instructions but found none. I don't know if
sudo apt-get install --reinstall ubuntu_browser is the correct instruction or not, so here I am asking.
